Congratulations.  You did good.  Very possible you are good to go.  Check before bed, but unless it comes back significant no further treatment is necessary.  Oil tricks are to reduce/eliminate froth.  Multiple reasons for bloat. Really think if it was going to be supper serious, calf would not have made it all day to get to this point.  Esophagus is non forgiving if one was to damage it, they do not heal very well so there is a danger to tubing an animal. Just like pouring anything down. Unless one knows what they are doing it is dangerous lesson to learn if the tube is in the stomach or the lungs.  Experience really helps improve the odds.  Really would not want to encourage one to tube unnecessary.  Popping the balloon, letting the gas off was the easy part. Good Job.
